Through Navy Phase I and Phase II SBIR programs, QuesTek Innovations LLC, Evanston, Ill., developed Ferrium N63, a nitridable stainless steel alloy for bearing, gear, and other wear-critical applications, that demonstrates a unique combination of high-surface hardness, fatigue life, thermal resistance, core strength and ductility, including down to cryogenic temperatures.
Oerlikon Metco Coating Services announced its new laser cladding service center is fully operational in Huntersville, N.C., a suburb of Charlotte.
Invisibility devices may soon no longer be the stuff of science fiction. A new study published in the De Gruyter journal Nanophotonics by lead authors Huanyang Chen at Xiamen University, China, and Qiaoliang Bao, suggests the use of the material Molybdenum Trioxide (a-MoO3) to replace expensive and difficult to produce metamaterials in the emerging technology of novel optical devices.
Iron is an essential nutrient that almost all life requires to grow and thrive. Iron’s importance goes all the way back to the formation of the planet Earth, where the amount of iron in the Earth’s rocky mantle was ‘set’ by the conditions under which the planet formed and went on to have major ramifications for how life developed.
The field of self-repairing materials is rapidly expanding, and what used to be science fiction might soon become reality, thanks to Technion — Israel Institute of Technology scientists who developed eco-friendly nanocrystal semiconductors capable of self-healing.
